DNS Spoofing: Definition & Protection
DNS spoofing is a less-known yet highly dangerous threat. In today’s article, we aim to explain what the attack is, how it works, and most importantly, how you can protect yourself and your network from falling victim to this cyber threat. So, let’s begin!
What is DNS Spoofing?
DNS Spoofing (DNS cache poisoning) is a type of cyber attack where a hacker purposely corrupts the Domain Name System (DNS) cache with false information. This manipulation allows attackers to redirect internet traffic from legitimate websites to malicious ones without the user’s knowledge.
DNS is the system that translates human-friendly domain names (like www.example.com) into IP addresses that computers use to identify each other on the network. When you type a domain name into your browser, your device queries a DNS server to find the corresponding IP address. If a hacker successfully spoofs the DNS, they can modify this lookup process, directing you to a fake website instead of the real one.
